' STAVE-CQLUIVINQ i Be it known that I, GEORGE W. Locern, a citizen of the United States,-and a resident of Bellingham, in the county of Whatcom and State of Washington, (whose post-office address is Bellingham, Washington,) have invented certain new and useful Improvements in Stave-Columns, of which the following is a specification. I

;My invention relates to an improvement in stave-columns; and it consists in banding them with wire in such a manner that the wire band is out of the Way of the subsequent turning down required to finish the columns and. also far enough from the ends to be beyond where the column will be cut off before erecting.

Stave-columns are usually built of eight or more staves, properly beveled, .tongued, grooved, and glued together. Such columns are built either of straight or tapering staves,

and sometimes the staves are crowned in the middle. These staves are either made of one piece. or built up of twoor more pieces glued together. In whatever Way such columns are -made they have hitherto been liable to come unglued, especially .at the ends, thus.

rendering them unfit for the best use. My

inventionis-designed to obviate this difii- Qulty.

Inthe accompanying sheet of drawings,

Figure 1 is a plan view of the larger end of an eight-stave tapering column. Figs. 2 and 3 are a side elevation of the same with the C611. tral portion removed. Fig. 4 is a plan view of the smaller end of the same. Fig. 5 isa plan view of a portion of the larger end of. said column on a larger scale. Fig. 6is anelevation of the same. Fig. 7 is a sideelevation of a part of Fig. 6. Fig. 8 is an elevationof aportion of a piece removed from one of the staves shown in Figs. 5, 6, and 7. Fig. 9 is a plan view of one end of Fig. 8,. and Fig.

"10 is aside .elevation ofFig. 8.

This column is composed of the tapering staves Aa, Bb, Cc, Dd, Ff, Gg, and I-Ih, and

the parallel stave E e, all properly mitered,

tongued, and grooved. StaveAa is built up of a whole piece of Wood A, constituting the outer half, and a piece. a, which may be in two or more pieces side by side or abutted together, constituting the inner half of said stave. The other staves are built up in the same manner. The tongues and grooves are in the solid outer piece. In Figs. 5, 6, and 7 Dg is the groove in stave D. Et is the tongue lines in these figures.

in stave E. Eg is the groove instave E,'and

Ft is the tongue in stave F. Transversely through each stave are bored two small holes 0 and 0. These holes are located between the tongues and grooves and the inside of said outer pieces and are so placed that whenthe staves are assembled, as in Figs. 1, 2, 3, and 4, holes 0 in the several staves register with each other, and holes 0 similarly register with each other, as indicated in dotted band-saw a piece E is out from the outer side of one end of parallel stave E by making a cut in that end on a plane parallel with'the tongue and groove of this'stave and on the inside from said tongue and groove and'so" located that the saw passes through hole 0 only sufiicient to open said hole on the side nearest said tongue andgroove and alsoby cutting laterally across said stave from the By means of a thin" outside, making a kerf inclined at anacute angle with and meeting the ends of the aforesaid kerf. l r

In Figs. 5, 6, and 7, which illustrate a portion of staves D, E, and -F,.the surface R E was made by the first-mentionedcut,-while' the surface Eb was made by the second-mentioned cut. Piece E, which has been re- -moved by the said cuttin is shown in Figs.

8, 9, and 10, in which E?) is the surface made by said second cut. hole 0 left in this piece by said first cut.

Eg is the groove, and Et the tongue, on piece .9 the other end of stave E. Piece E resem- E. In the same way piece E is cut out'of bles piece E in every respect.

- In assembling such a column the surfaces E0 is a portion ofthe' of the staves which are toli'e together are smeared with glue and the staves are laid side by side in proper relation, outside downward, with stave E omitted. A wire W is then threaded through holes 0,. and a .wire W through holes 0. The outer edges of the .plat thus formed are bent upwardand suitable clamps loosely adjusted over thesame.

Then stave IE withpieces Eand E omitted is put. in its proper place and the clamps tightened to bring all joints snugly together. The ends of wire W are then twisted together with such force asto form a band in holes 0, which issnugly embedded in said holes, es-

pecially at the edges of the staves, as more plainly shown in the sections removed in Figs. 1 and 4. The twisted ends of this Wire are shown in dotted outline at X, Fig. 5.

Subsequently this twisted part is cut off to a IIO band around each end of a column.

suitable length and then bent down to lie in the hole 0 alongside of wire W, as indicated, at X,Figs. 2 and 5 and 6. Similarly the ends of wire 0 are twistedtogether and bent over to occupy the position illustrated at Y, Fig. 3 Pieces E and E are then properly smeared with glue and driven in their respective places to perfect the stave E. In addition to the glue each of these pieces E and E is held in place by the tongue and groove described and by the mitered inside end. After the glue is set the column is ready to be turned down to the finished size, when there will be no external indications of the concealed wire bands described. Should the glue in the joints soften by exposure to 'moisture, as frequently happens, these concealed bands will hold the staves in proper place, thus relieving the weakened glue of the strain that might otherwise cause the joints to open.

Parallel stave E is made equal in width to the mean width of the tapered staves, and the angle of the mitered edges is the same as in the other staves. Consequently the joints bet-ween E and its neighbors are .notperfect.

However, this difference is so slight that the elasticity of the wood easily makes it up. The larger the number of staves used the less becomes this difference. However, when it becomes objectionably large I use two paraliel staves in each column placed opposite each other, which makes the oining perfect.

In very short columns I cut out the outside of the parallel stave E its entire length when pieces E and E are merged into one. Some times I find it desirable to put more than one In this case I bore a set'of holes for each band desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is- 1. In a stave-column the combination of a number of tapering staves, the tapering ends of which lie in the same direction and one or more parallel staves.

2. Ina stave-column, the combination of a number of tapering staves; with a parallel stave; and a longitudinal piece cut from and reset in the outside of said parallel stave at each end of the same.

' 3. In a stave-column the combination of a number of tapering staves, with a parallel stave, there being transverse holes through said staves so placed that said holes may register in sets; and a longitudinal piece out from and reset in the outside of said parallel stave at each end of the same, said piece be- VVhatcom and State of IVashington, this ing cut deep enough to uncover one or more of said holes in said stave.

4-. In a stave-column the combination of a number of tapering staves; a parallel stave; a longitudinal tongue and groove in each stave to match with a groove and tongue in its neighboring staves; there being transverse holes through said staves nearer the axis of said column than said tongues and grooves and so placed that said holes may register in sets and each set form within the wall of said column the figure of a polygon; and a longitudinal piece cut from and reset in the outside of said parallel stave at each end of the same, said piece being cut from the full width. of said stave and deep enough to include the tongue and groove of that part of said stave, and, also deep enough to uncover one or more of said transverse holes, and the inner end of said piece is out on an acute angle.

6. In a stave-column the combination of a number of tapering staves, with a parallel stave; a longitudinal tongue and groove in each stave to match with a groove and tongue in its neighboring staves; there being transverse holes through each of' said staves nearer the axis of said column than said tongues and grooves and so placed that said holes may register in sets and each set form within the wall of said column the figure of a polygon; a longitudinal piece cut from and reset in the outside of said parallel stave at each end of the same, said piece being cut from the full width of said stave and deep enough to include the tongue and groove of that part of said stave, and also deep enough to uncover one or more of said holes in said stave, and the inner end of said piece is cut at an acute angle; and a wire in each of said sets of holes drawn tightly with its ends twisted together and bentdownward to lie in said hole.
